Remove unused trait imports
2016-04-15Implement `Default` for more types in the standard libraryTobias Bucher-1/+1

2016-03-22std: Change `encode_utf{8,16}` to return iteratorsAlex Crichton-14/+13
Currently these have non-traditional APIs which take a buffer and report how much was filled in, but they're not necessarily ergonomic to use. Returning an iterator which *also* exposes an underlying slice shouldn't result in any performance loss as it's just a lazy version of the same implementation, and it's also much more ergonomic! cc #27784
2016-03-20libcore: add Debug implementations to most missing typesSean McArthur-4/+28
2016-03-12std: Clean out deprecated APIsAlex Crichton-111/+12
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.
2016-03-08std: Fix rustdoc links with std::fmt::AlignmentAlex Crichton-12/+33
This is actually a reexported implementation detail in the `rt::v1` module but rustdoc doesn't like reexporting items from `doc(hidden)` modules. Do what we'd end up doing anyway from an API perspective and make a public-facing `enum` that can be retranslated under the hood if necessary.

2016-02-17fmt: Make sure write_fmt's implementation can use write_charUlrik Sverdrup-0/+4
It looks like the Adapter inside write_fmt was never updated to forward the write_char method.
2016-02-11Auto merge of #31479 - kamalmarhubi:fmt-pointer-unsized, r=alexcrichtonbors-5/+5
This allows printing pointers to unsized types with the {:p} formatting directive. The following impls are extended to unsized types: - impl<'a, T: ?Sized> Pointer for &'a T - impl<'a, T: ?Sized> Pointer for &'a mut T - impl<T: ?Sized> Pointer for *const T - impl<T: ?Sized> Pointer for *mut T - impl<T: ?Sized> fmt::Pointer for Box<T> - impl<T: ?Sized> fmt::Pointer for Rc<T> - impl<T: ?Sized> fmt::Pointer for Arc<T>
2016-02-08Implement fmt::Pointer for pointers to unsized typesKamal Marhubi-5/+5

2016-02-08Remove old #[allow(trivial_casts)] annotationsAlex Crichton-6/+0
These were added a long time ago but we long since switched the lint back to allow-by-default, so these annotations shouldn't be necessary.
2016-01-16std: Stabilize APIs for the 1.7 releaseAlex Crichton-2/+14
This commit stabilizes and deprecates the FCP (final comment period) APIs for the upcoming 1.7 beta release.

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-14/+9
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968

2015-10-25std: Stabilize library APIs for 1.5Alex Crichton-15/+8
This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)

2015-09-30Fix module links in std::fmt and the Rust book's documentation chapter.Ted Mielczarek-9/+9
The links in the rustdoc for several places in fmt were trying to link to the std::fmt module but actually linking to std, which was confusing. While trying to figure out why I noticed that the documentation chapter of the Rust book has examples that show this same bug (although it doesn't seem widespread in practice).

2015-08-09Replace many uses of `mem::transmute` with more specific functionsTobias Bucher-2/+2
The replacements are functions that usually use a single `mem::transmute` in their body and restrict input and output via more concrete types than `T` and `U`. Worth noting are the `transmute` functions for slices and the `from_utf8*` family for mutable slices. Additionally, `mem::transmute` was often used for casting raw pointers, when you can already cast raw pointers just fine with `as`.
2015-08-03syntax: Implement #![no_core]Alex Crichton-3/+3
This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The `#![no_std]` attribute now injects `extern crate core` at the top of the crate as well as the libcore prelude into all modules (in the same manner as the standard library's prelude). The `#![no_core]` attribute disables both std and core injection. [rfc]: https://github.com/rust-lang/rfcs/pull/1184
